Tenth playthrough and discovered that the Legendary Edition has a 100% repeatable, unavoidable crash bug in ME1 on Series X that triggers in the final Saren fight. EA/BioWare are aware. Still not fixed by August.
The game cannot be completed if your configuration of character and crew hit this bug. Absolutely criminal that this passed cert in this state. I believe there is every chance they will simply ignore it and leave the game in an unplayable state.
